A total of 390 banks, many of them community firms, still struggle to repay a Troubled Asset Relief Program recapitalization fund with no clear exit plan, according to the Special Inspector General of TARP.

"The status of those banks is one of the major issues facing TARP nearly four years after the financial crisis," according to a SIGTARP report sent to Congress Tuesday.

The entire TARP program is expected to cost taxpayers $60 billion, according to the most recent estimate, though this does not include $118.5 billion still owed through other programs.
